Should not be hooked up to ANY motor controllers and directly to the PWM port in the roboRIO.


➠ Motor Controller Varieties

It is possible to control all the motors above (except the servo) with the below motor controllers; however, the breakers used have to be able to protect the wires and provide enough power for the motor used. For example, it is possible to connect 16 gauge wire with a 20 amp CB to a talon, but would not provide enough power if connected to say a CIM. There are two side wires that connect to each motor controller: the M-/M+ and the V-/V+ side. The ‘M’ stands for Motor, which denotes the wires attached here should be the ones also attached to the motor. The other side connects to the PDB. In both cases, the power goes to the + and ground to the -. There is also a thin slot where PWM cables plug into from the Digital Sidecar, with its direction based on the small notations on the motor controllers (often, ground is facing the side marked with a ‘B’).
